A bending tube for an endoscope, which is provided inside a bending portion of an insertion portion of an endoscope and includes a plurality of bending pieces covered by a flexible tube body, the bending tube including a distalmost end bending piece connected to a distal end portion of an insertion portion, a proximalmost end bending piece connected to a flexible tube portion of the insertion portion, and a net-like tube covering an outer periphery of the plurality of bending pieces except the distalmost end bending piece and the proximalmost end bending piece and including a distal end part fixed to a first bending piece joined to the distalmost end bending piece and a proximal end part fixed to a second bending piece joined to the proximalmost end bending piece.

An endoscope system includes an image pickup device that picks up an image of an inside of a subject, and outputs two or more digital signals, an electro-optical conversion section that converts the two or more digital signals outputted from the image pickup device into optical signals, and outputs the optical signals, an optical transmitting section that includes two or more optical transmitting members, and is adapted to transmit, in parallel, by the two or more optical transmitting members, two or more optical signals outputted from the electro-optical conversion section, and an output selection section provided between the image pickup device and the electro-optical conversion section, and being capable of combining, and outputting to one optical transmitting member, the two or more digital signals that are supplied to the two or more optical transmitting members, based on a transmission state of data optically transmitted by the optical transmitting section.

A flexible tube used as a part of an insertion section which defines a central axis of an insertion apparatus to be inserted into a hole, the flexible tube includes: a helical tube comprising a closely-wound region including a concave-convex portion which is provided on each of a pair of edges of a strip-shaped member elongated along a longitudinal axis, and which alternately includes convex portions and concave portions on the concave-convex portion, wherein, in a state where the strip-shaped member is spirally wound, the convex portions of the concave-convex portions facing each other along the central axis are compressed to each other; and a cylindrical outer tube which covers an outer surface of the helical tube.

A towing device for endoscopy including a connecting portion connected to a wire of an endoscope to be moved, wherein a body of the connecting portion is broken when a set amount of tension or more is applied to the connecting portion; a guide portion including an inner path through which the connecting portion moves; a clip portion positioned at an opposite direction of the wire with respect to the guide portion and hooked by the connecting portion to be closed and grip body tissues; and an extension portion configured to move together with the guide portion and having a magnetic force.

An adaptor may include a shell and a plunger positioned at a first end of the shell and moveable between an undepressed state and a depressed state. The adaptor may further include a ramp extending from a second end of the shell and a carrier coupled to the ramp. In the undepressed state, the carrier may be located at a first position along the ramp, and wherein, in the depressed state, the carrier may be located at a second position along the ramp, wherein the second position may be closer to the second end of the shell than the first position.

A surgical instrument including: a main body; an elongated shaft tube connected to the main body, the shaft tube having at least one working channel tube arranged in an interior of the shaft tube, the at least one working channel tube extending in a longitudinal direction of the shaft tube; and a connection body coupled to a proximal end region of the main body; wherein a proximal end region of the at least one working channel tube is accommodated inside the connection body and is sealed with respect to the connection body.

One of two connector receiving parts of a processor for endoscope has a shutter mechanism configured to open a shutter by an external force, the shutter having a gap through which a connector-side connection end section passes, and being configured to partition a recessed space of the connector receiving part with respect to an outside. In addition, the processor for endoscope includes a lock mechanism configured to make the shutter into the locked state during a period when another connection end section on the connector side and a processor-side connection end section are connected, and release the locked state of the shutter when the connection between the other connection end section on the connector side and the processor-side connection end section is released.

A connector device for an endoscope that can stably operate an endoscope is provided. A connector device (10) includes a hollow exterior case (20), a shield case (22) accommodated in the exterior case (20), and a power reception unit (24) to which power is supplied from a power feed unit (216) of a processor device (200) in a contactless manner. The exterior case (20) has a side wall part (32D) that faces the power feed unit (216). The shield case (22) has an inner case wall part (23) that is disposed to face and be spaced apart from the side wall part (32D). The power reception unit (24) is disposed on the inner case wall part (23).

A connector device for an endoscope that can prevent infiltration of water into an exterior member is provided. A linear portion (46A) of an elliptical ring portion (46) of a connector exterior case (28) includes through-holes (50 and 52). An inner peripheral surface of the linear portion (46A) includes a semicircular groove (54) that connects the through-hole (50) and the through-hole (52) to each other. An outer peripheral surface of a linear portion (30A) of an elliptical ring portion (30) of a plug (26) includes a semicircular groove (56), and the groove (56) is disposed to face the groove (54) so that an insertion passage (58) is formed. A pin (60) is fitted into the through-hole (52) from the through-hole (50) via the insertion passage (58), and the pin (60) is fitted to the through-hole (50), the insertion passage (58), and the through-hole (52).
